CVE ID : CVE-2005-4348

Daniel Drake discovered a problem in fetchmail, an SSL enabled POP3,
APOP, IMAP mail gatherer/forwarder, that can cause a crash when the
program is running in multidrop mode and receives messages without
headers.

The old stable distribution (woody) does not seem to be affected by
this problem.
